Are these cats going to be a problem?

    Gents,

    I purchased a 2007 Sequoia from a dealer in Houston sight unseen. I got a bunch of pics, a couple of videos, and the Carfax. It was a single owner car until the dealer I purchased it from acquired it. I had it shipped. The body, paint, and interior are in fantastic shape, and there's almost no rust underneath. She does have a couple of issues that I need to work through, but I'm fine with that.

    The Carfax indicates it stopped passing the emissions check a few years ago. I believe the prior owner installed these things rather than OEM replacement cats. She threw P0420 and P0430 codes today.

    Are these even catalytic convertors? Are they going to be a problem?

    Thanks,

    The truck came with O2 sensor extenders on the downstream sensors. Any idea why? Should I remove them?

    Thanks,

    Looks like someone tried to cheat and never properly fixed it. Just my guess.
